It is said in Huangdi Neijing that "abstemious diet" is a very important principle of health preservation. In fact, the importance of this principle cannot be ignored. Have a regular life. What does "Chang" mean? It is often a fixed thing. Saying unchanged and saying changed sound contradictory. In fact, this is not contradictory at all. What do you mean, Youchang? The opposite of constancy is impermanence. We call death impermanent. What should people be like alive? Youchang In other words, people should have a fixed daily life and life rules. Why fix it? Because the changes of yin and yang in heaven and earth are fixed. Like the law of day and night. You see, it's winter now, and the winter solstice will be on February 20, 65438. On the solstice in winter, the days are short and the nights are long. What should I do at this time? People should sleep more.

Huangdi Neijing said: "You have to wait for the sun when you lie down at night and get up early." . In other words, when there is no sun, stop tossing and sleep more. Then wait until late in the morning to come out for activities. In other words, the rule of your life is to follow the sun. However, if you don't care about your body to practice, run and exercise when it is particularly cold in winter, you can survive without bad health; If you have physical problems, you are likely to have a sudden myocardial infarction on the solstice of winter. You see, Mr. Ma Ji, a crosstalk master we are very familiar with, died in the bathroom on the morning of the winter solstice. Mr. Ma himself has heart disease, which Chinese medicine calls "insufficient heart fire". Winter belongs to water, and the winter solstice is the most abundant time for water vapor, so we must protect our hearts and protect the sun. The morning is the darkness before dawn, the bathroom is the worst and coldest place in the house, and then catching up with the winter solstice is the darkest day. Although we say "winter solstice produces the sun", on this day of winter solstice, although the spirit of the sun begins to sprout, on the other hand, its yin and cold are still the most vigorous.
